At this point our boat is ALMOST fully switched over to NMEA2000. But like you, our backup autopilot is an older model that only speaks NMEA0183.
We use an Actisense NGW-1 to convert the data on the NMEA2000 bus to a format compatible with NMEA0183. It translates the data on the new bus for our computer, and our old autopilot. It has worked well for us.
